Product Selling Points

1. Precise fastening guarantee: The unique design of torsional shear bolts can realize accurate pre-tightening force control, ensure that each connection point reaches an ideal fastening degree, and greatly enhance the stability and safety of the structure.
2. Excellent anti-loosening performance: The twisting design of the bolt head during installation fundamentally eliminates the possibility of loosening, and can maintain a stable connection even under long-term vibration and harsh environment.
3. Made of high-quality materials, it has excellent strength and corrosion resistance, can be used reliably for a long time, and reduces maintenance and replacement costs.Bolt

   Application :

    Torsional shear bolts are widely used in many important fields. In the steel structure building, ensure that the key parts such as beams and columns are firmly connected; In the wind power generation equipment, the tower, blades and wheels are fixed. It is also used in railway track, shipbuilding, large-scale mechanical equipment and petrochemical industry, and is an important part to provide reliable fastening.
